Le Nature Based Solutions nella regolazione dei flussi di energia e materia

The scientific community, in recent years, has been working hard to reduce energy consumption in building construction. However, we know that urban morphology can have a direct influence on energy consumption, as well as on the comfort of citizens. When we think about the circularity of production processes, we generally refer to the transformation of raw materials that have to be managed with a long-term vision, so that the resources do not lose value during their exploitation. The climatic events, considering them as resources, are however equally susceptible to a loss of quality, especially in the urban space. A "circular" approach to the exploitation of climatic resources sees the need to allow their use in a process as long as possible and without loss of quality in the path from the source (sun, rain, etc.) to what, otherwise, would constitute a “waste” or a disturbing element (wastewater, overheating, etc.). The research group that I represent in this paper, in its most recent activities - within the Department of Architecture and Design (DAD) of the University of Genoa (UNIGE) - considers NBS as the tool to achieve this goal.
